Microsoft is releasing for public download on Aug. 24 a new test build of its browser, the near-final Release Candidate 1 milestone. RC1 may or may not be the final public test build of IE 7, officials said, depending on tester feedback. Microsoft has said to expect the final version of its standalone browser to be available in the fourth calendar quarter of 2006. Microsoft is planning to push IE 7 out to users via its Automatic Update software-distribution mechanism that is used to deliver security patches to users.

Seems resonably snappy
